Miyero yekupisa ye ultrasonic inobatidzwa ne clamp-onkuwana chiyero chakarurama chekupisa kunopfuudzwa mumapaipi anotakura mvura kuburikidza nekusanganiswa kwekuyera kuyerera kwe ultrasonic uye kutarisa kusiyana kwekupisa. Kushanda kwavo kwakavakirwa pamisimboti ye acoustic uye thermodynamic, inosanganisira maitiro matatu makuru: kuyerwa kwekuyerera, kuona kusiyana kwekupisa, uye kuverenga kupisa & kuunganidza. Heino kupatsanurwa kwakadzama kwekushanda kwavo:
I. Zvikamu Zvikuru Nemabasa Azvo
Chiyero chekupisa che ultrasonic chinobata-bata chine zvikamu zvitatu zvakakosha zvinoshanda pamwe chete, chimwe nechimwe chine mabasa akasiyana:
- Ma sensor ekuyerera kwemvura anonamirwa ne ultrasound: Ane basa rekuyera mwero wekuyerera kwemvura panguva imwe chete mupaipi. Anoiswa kunze kwemadziro ekunze epaipi inoburitsa mvura (kana inodzosa mvura) pasina kubata mvura.
- MaSensor ekupisa: Kazhinji maSensor maviri ekudzivirira kupisa kweplatinum (semuenzaniso, PT1000 ine kururama kwe±0.1℃), akaiswa pamapombi ekupa nekudzorera mvura kuti aongorore kupisa kwemvura inopihwa (T1) uye kupisa kwemvura inodzorerwa (T2) munguva chaiyo.
- Mugadziri (calculator): Anogamuchira zviratidzo zvekuyerera uye tembiricha, anoverenga kupisa achishandisa maalgorithms akavakirwa mukati, uye anobata kuratidzwa kwedata, kuchengetwa, kana kutapurirana.
II. Matanho Ekushanda Akadzama
1. Kuyera Kuyerera: Kubata Kumhanya Kwekuyerera uchishandisa Ultrasonic Time-Difference Method
Chinoongorora kuyerera kwemvura chinonzi clamp-on ultrasonic ndicho chinhu chikuru pakuyera kuyerera kwemvura, chinoshanda nepfungwa imwecheteyo seye clamp-on ultrasonic flowmeters:
- Kuiswa kweSensor: Matransducer maviri eultrasonic (transmitter nereceiver) akasungirirwa zvakaenzana pamadziro epombi yekunze achishandisa maclamp, zvichigadzira nzira mbiri dzekuparadzira acoustic - imwe iri munzira yekuyerera kwemvura (pasi) uye imwe iri pairi (kumusoro).
- Kutumirwa kweChiratidzo uye Kugamuchira: Chinotumira chinoburitsa masaini e ultrasonic nenzira dzakasiyana-siyana munzira dziri pasi nedziri kumusoro. Sezvo mafungu eruzha achipararira nemumvura, nguva yekufamba kwawo inokanganiswa nekumhanya kwemvura: masaini epasi "anotakurwa" nekuyerera, zvichikonzera nguva pfupi yekufamba; masaini ekumusoro "anodziviswa," zvichikonzera nguva yakareba yekufamba.
- Kuverenga Mwenje neKuyerera: Mugadziri wemhepo anoyera musiyano wenguva (Δt) uye anoverenga mwero wekuyerera kwemvura pakarepo (v) achishandisa maparamita akadai sedhayamita yepombi nezvinhu. Mwenje uyu unozoshandurwa kuita mwero wekuyerera kwemvura pakarepo (qv) uye, pakupedzisira, kuita mwero wekuyerera kwemvura (qm) uchishandisa mwero wekuyerera kwemvura.
2. Kuyera Musiyano weTembiricha: Kubata Musiyano weSimba Pakati peKupa neMvura Inodzoka
Ma sensor ekupisa anobatanidzwa pamadziro ekunze emapombi ekupa nekudzorera (kana kuiswa pasina kukanganisa nzvimbo yekuyerera kwemvura) kuti atore tembiricha yemvura panguva chaiyo:
- Tembiricha yemvura inopihwa (T1): Inomiririra tembiricha yekutanga yemvura inopinda musystem yekutsinhana kwekupisa (inotakura simba rakawanda).
- Tembiricha yemvura inodzoka (T2): Inomiririra tembiricha yemvura inobuda musystem mushure mekutsinhana kwekupisa (nesimba rakaderera, nokudaro tembiricha yakaderera).
- Kuverenga Musiyano weTembiricha: Mugadziri wetembiricha anoramba achiverenga mutsauko (ΔT=T1−T2). Musiyano mukuru wetembiricha unoratidza kuti kupisa kwakawanda kunopfuudzwa panguva imwe neimwe.
3. Kuverenga Kupisa: Kuunganidza Kupisa Kwose Zvichibva paForamu dzeThermodynamic
Ichishandisa data rekuyerera uye musiyano wekupisa, host inoverenga uye inounganidza kupisa kwese panguva chaiyo ichishandisa fomura yekuyera kupisa kwepakati:Q=∫t1t2qm⋅cp⋅ΔTdt
Kupi:
Kupi:
- Q ndiyo kupisa kwakaunganidzwa (yuniti: kWh kana GJ);
- qm ndiyo mwero wekuyerera kwehuwandu hwemasero panguva imwe chete (kg/h);
- cp ndiko kugona kupisa kwemvura painomanikidzwa nguva dzose (yemvura, kazhinji);
- ΔT ndiyo musiyano wekupisa pakati pemvura inopihwa nemvura inodzoserwa (℃);
- Chiratidzo che integral chinomiririra kuunganidzwa kwenguva (t), kureva, kupisa kwese kunopedzwa kubva pakutanga kwekuyerwa kusvika pari zvino.
Muchidimbu, kupisa = mwero wekuyerera kwehuwandu × kugona kupisa kwakanangana × musiyano wekupisa × nguva. Mugadziri anoramba achitarisa uye achiunganidza kukosha uku kuti awane kupisa kwese kunodyiwa nemushandisi.
III. Kuburitswa kweData uye Mashandisirwo
Iyo host inoratidza data renguva chaiyo senge mwero wekuyerera kwemhepo ipapo ipapo, kupisa ipapo ipapo, kupisa kwakaunganidzwa, uye musiyano wetembiricha pachidzitiro chayo. Inotumirawo data kumasisitimu ekutonga kuburikidza nema interfaces akadai seRS485 kana NB-IoT, inotsigira maapplication akadai sekubhadhara kupisa uye manejimendi esimba.
Pfupiso
Pfungwa huru ye clamp-on ultrasonic heat meters inogona kupfupikiswa seizvi: "kuyera kuyerera ne ultrasound, kuona kusiyana kwekupisa ne sensors, uye kuverenga kupisa ne algorithms". Dhizaini yavo isingapindiri inobvisa kukuvara kwepaipi uye kupindirana kwemvura, nepo kusanganiswa kwetekinoroji ye ultrasonic nekutarisa tembiricha kuchivimbisa kuyera kwakarurama munzvimbo dzakasiyana siyana dzekufamba uye mamiriro akaoma ekushanda, zvichiita kuti zvishandiswe zvakanyanya mukubhadhara kwekupisa uye manejimendi esimba.
